ESTIMATING AND ANALYZING THE COSTS OF EGGPLANT (SOLANUM MELONGENA) PRODUCTION UNDER THE GREENHOUSE IN ANBAR GOVERNORATE FOR THE AGRICULTURAL SEASON 2019-2020

Abstract

: The research aimed to estimate and analyze the costs of eggplant production under the greenhouses in Anbar governorate for the agricultural season 2019-2020 depending on field data for 12 random samples of eggplant farms under the greenhouses of Anbar Governorate. The analysis results showed that the fixed costs constituted about 38.48%, while the variable costs constituted about 61.52% of the total costs, and the average production costs in the research sample amounted to 192240 dinars/ton. The long-run cubic function was the best among the functions that express the relationship between production costs as a dependent variable and production. Besides, the number of greenhouses in the farm independent variables, due to their similarity with the logic of the economic theory. The adjusted R 2 in it reached 0.9, where it was found that the optimal size of the farm represented by the number of greenhouses in it is 2.5 greenhouses. Thus, it achieved the optimum production size of 18 tons/farm, with an average cost of about 175000 dinars/ton. Furthermore, 50% of the farmers in the study sample achieved economies of scale, while 8.4% do not achieve any economies of scale, while the percentage of farmers who achieve low rates of economic efficiency is about 41.6 %. Finally, the supply function shows that the elasticity of supply decreases with increasing production, this means that the farms have great difficulty controlling production if prices change.
